According to oneiromancy, dragon dreams symbolize a struggle against surrendering to anger. The doctrine claims that such dreams force the dreamer to face suppressed rage. Souya Kuroi wakes from a nightmare where an enormous dragon devours everything in rainbow‑tinted light. He learns he lost parents and memory in a strange accident, turning waking life into another nightmare. With only that dream as memory, he relies on two guardians: the energetic maid Ginko and a huge cat called "Sensei." Ginko, always cheerful, tends to him with unwavering devotion while Sensei watches from afar.
His world flips when Saromisaka City faces a teddy‑bear‑shaped UFO. Saromisaka City, known for bustling markets, is threatened. The UFO hovered above, rattling the streets. Military fails, so seven mysterious figures rise to fight the menace. They destroy the invader with rainbow‑colored lights, identical to those Souya saw in his dream. The seven heroes coordinate their attacks in a dazzling display.
After the alien threat is repelled, the seven heroes confront a new foe: Souya. Vowing vengeance on those who shattered his past, he launches a campaign against the "heroes," drawing a galactic conflict. Souya's vow of vengeance is fueled by the memory of his ruined past.
